Dave G3UUR pointed me in the direction of the 1961 American Heathkit catalogue in which I found the EW19 electronic workshop kit. My memory had this as the EW1, but I must have got this wrong. My mum and dad bought me this for Christmas 1961 and it was this that got me started in radio as a hobby. The Medium Wave radio was used for my first DXing late in the evenings. Also, the simple MW transmitter (using the crystal earpiece as a mic) got me across the house - my first transmissions.
